The function T(g) = 5200 + .25(G-32000) signifies federal income tax T (in dollars) for filer whose modified adjust gross income is G dollars where 32,000 < G < 72,250. (That is a greater than or equal to)
[5200,15262.5]
Determine the domain of T:
Determine equation which gives adjust gross income G as the function of federal income tax T: [t+2800]/.25 =G
Give domain of G: [5200,15262.5]
Give range of G: [32,000,72,250]
